Obsolete RetryPolicy code for Azure blob storage

I am coding an MVC5 application, and am uploading BlockBlobs to Azure.

I have some Microsoft code that is now obsolete, and I wish to convert this obsolete code to code that will work in my application.

Here is the old code:

BlockBlob.PutBlock(blockId, chunkStream, null, null, new BlobRequestOptions() { RetryPolicy = RetryPolicies.Retry(3, TimeSpan.FromSeconds(10)) });

I have code that does work, however this code does not use a RetryPolicy.

Here is the code with no RetryPolicy:

BlockBlob.PutBlock(blockId, chunkStream, null, null, null, null);

Can I please have some help to construct the BlobRequestOptions object correctly that uses a RetryPolicy?

Here is what I have so far:

BlobRequestOptions blobRequestOptions = new BlobRequestOptions();
blobRequestOptions.RetryPolicy.CreateInstance();
TimeSpan timeSpan = new TimeSpan();
TimeSpan.FromSeconds(10);
blobRequestOptions.RetryPolicy.ShouldRetry(3, 0, new Exception(), out timeSpan, new OperationContext());

I am not sure of the following:

  1. What status code to use.
  2. What to use for the LastException.
  3. The out value for the timespan.
  4. What to use for OperationContext.

Thanks in advance.

I had a similar issue. Microsoft.WindowsAzure.StorageClient is deprecated, you now need to use Microsoft.WindowsAzure.Storage or more specifically the Microsoft.WindowsAzure.Storage.RetryPolicies.

For that retry, this should work

new BlobRequestOptions() { RetryPolicy = new LinearRetry(TimeSpan.FromSeconds(10), 3) }
